R. STEEL, a residing at ful Improvements 1n Heat-Insulating Tubes p or Receptacles, of which the following is a specification.

This invention relates to inclosures for bottles containing liquid o'r the like that is to be maintained for an indefinite period atthe same temperature as that at which 1t was placed in the bottle.

The invention has for one of its objects to improve and simplify the construction of receptacles or inclosures of the character referred to so as to be comparatively simple and inexpensive to manufacture and'of such design as to effectively insulate the contents of the inclosed bottle or container from the surrounding atmosphere. y

`With such and other objects in view, as will appear as the description proceeds, the invention comprises=the various novel features of construction and arrangement of parts which will be more iereinafter and set forth with particularity in the claim appended hereto.

In the accompanying drawing, which illustrates one embodiment of the invention, Figure 1 is a vertical central section of the receptacle. ig. 2' is a side view thereof with the cover raised from the body of the receptacle B5 v Similar reference characters are, employed to designate corresponding parts throughout the views. y

Referring tothe drawin A designates the body of theinsating tu e or receptacle, and B, the coveoplgsnre therefor, the receptacle or tube being 'slrown empty, but it is to be understood a. glass bottle or other container shaped to" lf'thebody A is adaptedhto be used in connection with the tube or receptacle.

lThebody A consists of inner and otiterv cylindrical shells 1 and 2 that are of ldiiferent diameters so as to provide an intervening chamber which is iilledwith cork, as-

bestos or other materlal B'that is a non-conductor lof heat, 'and the bottom 4 ofthe inner shell is spaced above the bottom 5 of,

the o'uter/ shell so can also be illed rial 3. The upper led Vformed with an outstan that the intervening space with the insulating matee of the shell 2 is ing annularange 6 of Cuyahoga and' State of Ohio, have invented new and useu fullyV described Vthat such changes may which not 4onlyreinforces the outer shell but 'forms means' whereb the inner shell can b e joined thereto. he up er end of the inner shell 1 projects out o the outer shell and has a downwardly bent truncated ortion or flange 7 and the widest part of this truncated portion is of substantially the same diameter as the outer shell. The bot* tom edge of the truncated portion 7 is curled outwardly around and under the flange 6 on the outer shell in the form of a bead 8 so as to form a joint between the inner and outer shell and also stiifen the u perV end of the body A. The conical surace formed by the flange or truncated portion 7 is provided with screw threads 9 so as to secure the cover or closure B to the body A.

The cover or closure B consists f inner and outer shells 10 and 11 which are also of different diameters so as to rovide an interyening chamber that is fille with noncondiicting material 12 that extends also between the tops or heads 13 and 14 of the shells. The bottom portion of the inner shell 10 flares downwardly so as to be of the same diameter as the outer shell,.and the bot-tom edge 15 of this iared portion is curled outwardly and upwardly around the bottom edge of the outer shell and can be soldered thereto to form a strong joint. rIll-ie flared or conical portion of the inner shell is, shaped to snugly fit the tapered upper end of 4the'body A, and it is also provided with threads 16 for engaging the threads 9.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily ap parent. to these skilled in the art to which the invention appertains', and while-I have described the principle of operation of the invention, together-with the device which I now consider to be the best embodiment thereof, I desire to have understood, tlai the device shown is merelfyiillnstrativauand v be made whenrdesind as are`witghin the appended hereto.

,Having 4thus described. the invention, what I .claim as new, is y A tube or receptacle inner and outer she -ofdiierent diameters, insulating matea1 ling between the' shells` an ann edge of the outer body `consisting of' 'scope ofthe claim I the inner shell being. turned downwardly to form a truncated fiange, an annular bead at the lower edge of the truncated flange arranged in clamping engagement with the flange at the upper end of the outer shell;v and a .closure consisting of inner and outer shells of different diameters, insulating material between the shells, the inner shell being` extended downwardly at an angle toward the lower extremity of the outer shell and contacting with the truncated flange on the said first named inner shel1,.the outer` shell of the closure being formed at its lower end with a peripheral flange, and the said outer s ell of the closure and which` frietionally binds against the first named bead when the closure is in a closed osition.

In testimony whereof I affix my slgnature in presence of two witnesses.
